Title of Document: THERMO-MECHANICAL DESIGN STUDY OF FIBER OPTIC PRESSURE SENSOR DIAPHRAGMS. Yasir Majeed, Master of Science, Mechanical Engineering, 2009 Directed By: Professor Abhijit Dasgupta, Department of Mechanical Engineering This thesis parametrically explores the nonlinear design sensitivity of a fiber optic pressure sensor (FOPS), based on selected thermo-mechanical failure mechanisms...

We analyze a fiber-optic component which could find multiple uses in novel information-processing systems utilizing squeezed states of light. Our approach is based on the phenomenon of photon-number squeezing of soliton noise after the soliton has propagated through a nonlinear optical fiber. Applications of this component in optical networks for quantum computation and quantum cryptography are...

An electro-optic silicon modulator with negative electrical power dissipation is proposed. The device performs optical modulation through electrical control of losses caused by two photon absorption. It further exploits the nonlinear photovoltaic effect to recover the optical power that is normally dissipated when the modulator is in the on state.

Optical wavefront interferometry has evolved into increasingly compact and portable forms with optimizations and novel developments from multi-component, bulk-optic configurations to miniaturized multi-core fiber forms; each presents its own advantages, challenges and opportunities. OCIS codes: 030.0030 Coherence; 070.0070 Fourier optics and signal processing; 120.0120 Instrumentation, measurem...

The impact of pump pulse fluctuations on ultrafast nonlinear frequency conversion processes in optical fibers is investigated. A simple measure the sensitivity a particular process to technical noise introduced and tested against numerical ensemble simulations for normal-dispersion continuum generation dispersive-wave generation. proposed found adequately describe at per mill or percent level.

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...
